My Frenchie is a crazy chewer and can chew up a nylabone in a day, so I was looking for something that would last longer. So far this is holding up, and is pretty durable. Both my dogs like it a lot, it’s easy for them to grasp, and chewable but still very tough material. I suspect at some point it’ll wear down, but not for a while. The size was just as described / expected. Not too small and not too big

NOT FOR PLAYING CATCH.

Color: Blue

This toy is quite heavy, making it good for a chew toy or for fetch, but not for catch. It could very easily injure your dog as it damned near did mine.
